modelCISESim2States120501

Extends from Modelica.Icons.Example (Icon for runnable examples), Models.CISESim2States (CISE plant reduced model with boundary conditions and initial steady-state computation).

Information

This model extends CISESim2States with the appropriate steady-state values of the boundary conditions for the 120501 transient.

This model must be simulated for 20000 s to obtain the required steady state. The actual transient can then be simulated by importing the final steady state, setting the controller gains to zero, and setting the appropriate values to the signal generators height parameters:

importInitial()

ValveOpening.steadyStateGain=0.0
wfeed.steadyStateGain=0.0

Qev.startTime={63};
Qev.height={-11.4e3};
Qev.duration={7};
wfeed1.startTime={63};
wfeed1.height={0.0017};
wfeed1.duration={16};
wfeed2.startTime={80};
wfeed2.height={0.0009};
wfeed2.duration={540};

The whole simulation sequence can be obtained by running the 120501_2s.mos Dymola script.
